.To all whom t may concern:

.Be it known that I, JHANN BERNINs., a subject ofthe King of Prussia, residing at 88u berloilker Allee, Dusseldorf, 1n the Kingdom of Prussia and German Empire, have invented certain new and usefullmprovements in Compressed-Air D1str1butlng or Regulating Devices for Pulsometers and Similar Apparatus, of which the following is a specification.

The present invention has for its object a compressed air controlling device for pulsometers and similar apparatus" for elevab ing liquids of all kinds.

The new controlling device comprises a ressure .yessel which is located between the liquid storage reservoir and the point to which the liquid is to be conveyedand the device is so constructed that the aircontained in the said pressure vessel is compressed by the liquid to be elevated, while the -thus compressed air is employed for controlling the access of a fluid pressure 'medium (compressed air or the like) to the pressure' vessel.

' In ,pulsometers and similar apparat-us hitherto employed the access of the compressed air for forcing up the liquid has geneially been controlled by means of floats.`

Movements of such floats are transmitted through a long rod to acomplicated mechanism acting to control the access of the crllilie chief defects of these old controlling devices are as follows: their height is considerable, the distributing gear is complicated and the movable parts wear out speedily, especially when acids have to be raised, thus causing a large expenditure for repairs.

To avoid these defects is the object of my invention in which an extremely simple co'ntrolling device'is used which does not come in Contact with the liquid t0 be elevated but can belocated at any suitable place beyond the reach of the liquid. Any convenient vessel -can be used as the pressure vessel.

The compressed air controlling device ae4 -cording to my invention is illustrated by way of example in the accompanying drawing, in Whichz- Figure l shows diagrammatic-ally the entire. apparatus for raising liquid together with the compressed air controlling' device. ira 9, AQhnvvs the controlling device proper specification of Letters Patent.

rise of the liquid the air contained in o iscompressed'. Vlheny the vessel c is nearly filled the air therein is compressed to such an extent that, through the connectingV pipe Lit is able to actuate the controlling valve z' arranged intermediate between the storage tank as and the place to which the liquid is to be conveyed so that the compressed air I supplied from a compressor or air reservoir (not shown) through said valve z' will enter the pressure vessel c. rllhe liquid therein then is forced up in the pipe f and Hows into the tank g to which the liquid is to be conveyed. As soon as the elevation of the liquid into the tank g has been completed, that is to say at the moment at whiehthecompressed air begins to escape at g, the valve e' automatically shuts ofi' 4further'access of compressed air to the vessel a through pipe d. The vessel c is then again filled fromthe reservoir a and the above described operation begins once more. By closing the cock zin the compressed air supply pipe c. the entire apparatus can be rendered inoperative at any time.

` The distributing or controlling device proper consists of the valve z' with the pipe connections f for the entrance of the compressed air and l for the escape of the compressed air into the pipe al conducting the air to the pressure -vessel c", the screwed coverm, the movable piston n, which at its lower part is reduced in diameter so as to present a smaller area to the compressed therein and entering the distributing` dev-ice at l has attained such a degree of pressure that 1t will force the piston n upward. lm-

mediately high pressure compressed air enters through the bore in the nipple l?, and

. passes through the bore in the nipple Z intothe pipe d and thevessel c. When all the liquid l1 said vessel has been forced up through'pipe f into the tank g the compressed air will escape from the 'pipe fat ple Ic, thereby shutting4 off further supply of' compressed air to the vessel c.

WhatV I claini is': l Y In compressed air controlling device for pulsometers and like apparatus, the combination wltll a llquld storage reservolr, of a closed pressure Vessel adapted to r'eceive liquid from sald reservon', a llqlucl elevat- .ng -p1pe entering said pressure vessel, a

compressed air lsup-ply pipe connected to the pressure vessel, andA n controlling device at the other end of sazl air supply pipe, comprising a movable piston havinga reduced portion and adapted t'o be operated by theai'r in said pressure vessel .upon the compression of said air by the milowing liquid, so as to open a passage to said' pressure vessel from a source of a pressure medium, such as compressed air, and a Weiglit connected to sind plston to return the same to inoperative position-upon the eXhau'st'of the pressure medium.

I In test1r nony'whereofl` have affixed my slgnature 1n presence of Wltnesses.
